Description

Technical Field

[0001] This application relates to the field of data processing technology, and more specifically, to an alarm compression method, apparatus, device, and readable storage medium. Background Technology

[0002] With the rapid development of services such as the Internet, 5G, and computing power, the scale of optical transmission networks has expanded dramatically, and network topologies have become increasingly complex. Against this backdrop, once a physical layer fault such as a fiber optic cable break occurs in an optical transmission network, its impact propagates along the network signal flow path, instantly triggering dozens or even hundreds of derivative alarms indicating port performance degradation and signal loss on transmission systems of different technical architectures, such as OTN, DWDM, and SDH. These alarms are numerous, redundant, and scattered across different levels of network management systems, forming an "alarm storm" that greatly hinders maintenance personnel from quickly locating the root cause of the fault. Existing technologies often utilize neural networks to compress and merge highly similar alarms based on their similarity, in order to accelerate the location of the root cause of the fault. However, the alarm formats, identifiers, and representation methods differ significantly across different technical architectures, making it difficult to guarantee the reliability of alarm compression when using neural networks. Therefore, how to provide an alarm compression method applicable to multi-technical architecture hybrid networks has become a key focus for those skilled in the art. Summary of the Invention

[0023] Based on the topological connection relationship between different network element boards and the port connection relationship within different communication stations, an intra-station transmission link storage table is constructed.

[0024] Optionally, the step of determining all adjacent ports affected by the interruption of the target optical transmission link by taking each target transmission topology segment as the transmission starting point, and combining the logical bearer link information in the information storage table and the intra-site transmission link information, includes:

[0025] The physical ports corresponding to each target transmission topology segment are designated as adjacent ports.

[0026] Based on the information storage table, it is detected whether each target transmission topology segment corresponds to a subsequent transmission topology segment and / or a bearer transmission topology segment; if so, multiple adjacent ports are determined based on the subsequent transmission topology segments and bearer transmission topology segments of each target transmission topology segment.

[0027] Optionally, the step of detecting whether each target transmission topology segment corresponds to a subsequent transmission topology segment and a bearer transmission topology segment based on the information storage table includes:

[0028] For each target transmission topology segment, find all target OMS paths and all target OCH paths carried in the target transmission topology segment as the carrying transmission topology segment of the target transmission topology segment; determine whether the target transmission topology segment belongs to an intermediate relay segment in the corresponding target OMS path. If so, take all OTS channels in the corresponding target OMS path that are subsequent to the target transmission topology segment as each subsequent transmission topology segment.

[0029] Optionally, the determination of multiple adjacent ports based on the subsequent transmission topology segments and the bearer transmission topology segments of each target transmission topology segment includes:

[0030] For each bearer transmission topology segment, determine the communication station matched by the bearer transmission topology segment; take the signal port of the bearer transmission topology segment in the communication station as the in-station transmission start point, and determine the corresponding in-station transmission endpoint based on the inter-board topology connection relationship and the cross-connection relationship between the in-board ports within the network element.

[0031] All ports in the protection groups corresponding to each target OMS path and each target OCH path, the source and destination ends of each subsequent transmission topology segment, and the in-station transmission start and end points of each carrying transmission topology segment are treated as multiple adjacent ports.

[0032] An alarm compression device, comprising:

[0033] The target physical destination determination module is used to determine the target physical destination that matches the target optical transmission link when it is confirmed that the target optical transmission link has been interrupted.

[0034] The information storage table acquisition module is used to acquire the information storage table that records physical transmission link information, logical bearer link information and intra-site transmission link information in the optical transmission network.

[0035] The target transmission topology segment determination module is used to determine, based on the physical transmission link information in the information storage table, all target transmission topology segments connected to the target physical destination port that are affected by the interruption of the target optical transmission link;

[0036] The adjacent port determination module is used to determine all adjacent ports affected by the interruption of the target optical transmission link by taking each target transmission topology segment as the transmission starting point in turn, and combining the logical bearer link information in the information storage table and the intra-site transmission link information.

[0037] The alarm merging module is used to merge the alarm information matching each adjacent port into the derived alarm information of the target optical transmission link interruption.

[0038] An alarm compression device includes a memory and a processor;

[0040] The processor is used to execute the program to implement the various steps of the alarm compression method described above.

[0041] A readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the alarm compression method described above.

[0042] As can be seen from the above technical solutions, the alarm compression method provided in this application can obtain an information storage table that records physical transmission link information, logical bearer link information, and intra-site transmission link information in an optical transmission network. This information storage table, combined with the physical and logical layers, is used to determine the transmission network link, facilitating subsequent multi-dimensional lookup of adjacent ports using both physical and logical layers. When this application confirms that a target optical transmission link has been interrupted, the target physical destination port matched by the target optical transmission link can be determined. Based on the physical transmission link information in the information storage table, all target transmission topology segments connected to the target physical destination port affected by the interruption of the target optical transmission link are determined. Then, taking each target transmission topology segment as the transmission starting point, and combining the logical bearer link information and the intra-site transmission link information in the information storage table, the target optical transmission link affected by the interruption is determined. This application identifies all adjacent ports affected by the interruption of the optical transmission link. Therefore, by combining an information storage table, it can search for matching target physical destination ports from the physical layer based on the target optical transmission link, then identify the first-level affected target transmission topology segments from the target physical destination ports, and finally, using each target transmission topology segment as a transmission starting point, combined with the logical bearer link information and intra-site transmission link information in the information storage table, it can find all transmission physical ports affected by the interruption event according to the actual signal flow. Subsequently, this application merges the alarm information matched by each adjacent port into derived alarm information of the target optical transmission link interruption. Based on this, this application can directly locate all transmission physical ports in the optical transmission network affected by the target optical transmission link interruption event, and compress and merge the alarms of all affected transmission physical ports, thereby compressing related alarms in the same optical transmission network under different technical systems. As can be seen, this application can automatically trigger alarm compression after determining that an interruption event has occurred in the target optical transmission link. This enables the merging and compression of related alarms caused by the interruption of the same target optical transmission link under different technical systems in the same optical transmission network. It does not involve analyzing and processing the specific alarm content. Therefore, even if the alarm format, alarm description, and alarm keywords are updated and iterated, it will not affect the application of this application, thus improving the applicability and practicality of this application.

[0043] Furthermore, this application transforms the traditional approach of "post-hoclyptic root cause analysis from massive alarms" into "starting from a definite physical layer fault and performing a positive, deterministic deduction of the impact." This is a fundamental innovation in thinking, ensuring the accuracy and timeliness of the results.

[0044] Furthermore, this application unifies the modeling and storage of physical transmission link information, logical bearer link information, and intra-site transmission link information in the optical transmission network, constructing a complete analytical data foundation. By taking each target transmission topology segment as the transmission starting point, and combining the logical bearer link information and the intra-site transmission link information, it achieves accurate diffusion analysis of fault impacts in different directions within the same site, as well as along the optical path to subsequent network elements, covering all indirect impact scenarios and maximizing compression efficiency and effectiveness.

Obviously, the drawings described below are only embodiments of this application. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.

[0048] Figure 3 This is a hardware structure block diagram of an alarm compression device disclosed in an embodiment of this application. Detailed Implementation

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] This application provides an alarm compression method that can be applied to various systems or systems, as well as to various computer terminals or smart terminals. The executing entity can be the processor or server of the computer terminal or smart terminal.

[0051] Next, combine Figure 1 The alarm compression method of this application is described in detail, including the following steps:

[0052] Step S1: When it is confirmed that the target optical transmission link has been interrupted, determine the target physical destination port matched by the target optical transmission link.

[0053] Specifically, the interruption of the target optical transmission link can be confirmed based on the received alarm information, cutover work orders, and / or maintenance work orders.

[0054] The target optical transmission link can be the optical fiber core matched with the alarm information, cutover work order and / or maintenance work order, or it can be the optical transmission section (OTS), optical supervisory channel (OSC) and transmission topology link matched with the alarm information, cutover work order and / or maintenance work order.

[0055] In practice, once a target optical transmission link is interrupted in an optical transmission network, it means that the optical information transmitted from the source end of the target optical transmission link cannot be transmitted to the destination end. At this time, it may be that the physical link of the target optical transmission link itself is interrupted, or it may be that the physical port of the target optical transmission link is faulty.

[0056] To simplify the analysis process, the destination port of the target optical transmission link can be directly used as the target physical destination port.

[0057] Step S2: Obtain an information storage table for recording physical transmission link information, logical bearer link information, and intra-site transmission link information in the optical transmission network.

[0058] Specifically, physical transmission link information may include relevant information about each OTS and each OSC in the optical transmission network;

[0059] Logical bearer link information may include the association information and protection group information carried by the physical layer in the logical layer of the optical transmission network;

[0060] Intra-station transmission link information can be used to describe the path a signal takes within each communication station.

[0061] Step S3: Based on the physical transmission link information in the information storage table, determine all target transmission topology segments connected to the target physical destination that are affected by the interruption of the target optical transmission link.

[0062] Specifically, based on the physical transmission link information in the information storage table, the OTS and OSC with the target physical destination as the source can be determined as each target transmission topology segment.

[0063] Step S4: Taking each target transmission topology segment as the transmission starting point, and combining the logical bearer link information and the intra-station transmission link information in the information storage table, determine all adjacent ports affected by the interruption of the target optical transmission link.

[0064] Specifically, by combining the information storage table, the direction of signal flow in the optical transmission network can be analyzed when each target transmission topology segment is taken as the transmission starting point. The transmission links and subsequent physical links carried on the target transmission topology segment can be determined, and the destination port of each target transmission topology segment can be determined as one part of the adjacent ports. The transmission physical ports of each transmission link can be determined as another part of the adjacent ports, and the transmission physical ports of each subsequent physical link can be determined as yet another part of the adjacent ports.

[0065] Step S5: Merge the alarm information matched by each adjacent port into the derived alarm information of the target optical transmission link interruption.

[0066] Specifically, "the target optical transmission link is interrupted" can be marked as a root cause alarm, and the alarms related to each adjacent port generated can be grouped as their derived alarms and output to the application presentation layer.

[0067] As can be seen from the above technical solutions, the alarm compression method provided in this application can obtain an information storage table that records physical transmission link information, logical bearer link information, and intra-site transmission link information in an optical transmission network. This information storage table, combined with the physical and logical layers, is used to determine the transmission network link, facilitating subsequent multi-dimensional lookup of adjacent ports using both physical and logical layers. When this application confirms that a target optical transmission link has been interrupted, the target physical destination port matched by the target optical transmission link can be determined. Based on the physical transmission link information in the information storage table, all target transmission topology segments connected to the target physical destination port affected by the interruption of the target optical transmission link are determined. Then, taking each target transmission topology segment as the transmission starting point, and combining the logical bearer link information and the intra-site transmission link information in the information storage table, the target optical transmission link affected by the interruption is determined. This application identifies all adjacent ports affected by the interruption of the optical transmission link. Therefore, by combining an information storage table, it can search for matching target physical destination ports from the physical layer based on the target optical transmission link, then identify the first-level affected target transmission topology segments from the target physical destination ports, and finally, using each target transmission topology segment as a transmission starting point, combined with the logical bearer link information and intra-site transmission link information in the information storage table, it can find all transmission physical ports affected by the interruption event according to the actual signal flow. Subsequently, this application merges the alarm information matched by each adjacent port into derived alarm information of the target optical transmission link interruption. Based on this, this application can directly locate all transmission physical ports in the optical transmission network affected by the target optical transmission link interruption event, and compress and merge the alarms of all affected transmission physical ports, thereby compressing related alarms in the same optical transmission network under different technical systems. As can be seen, this application can automatically trigger alarm compression after determining that an interruption event has occurred in the target optical transmission link. This enables the merging and compression of related alarms caused by the interruption of the same target optical transmission link under different technical systems in the same optical transmission network. It does not involve analyzing and processing the specific alarm content. Therefore, even if the alarm format, alarm description, and alarm keywords are updated and iterated, it will not affect the application of this application, thus improving the applicability and practicality of this application.

[0068] Furthermore, it can also highlight the target optical transmission link and all affected target transmission topology segments and adjacent ports in the form of a visual topology map, and / or generate a comprehensive fault work order covering all affected target transmission topology segments and adjacent ports and their related services.

[0069] In some embodiments of this application, considering that the interruption event of the target optical transmission link can be confirmed in multiple ways, multiple confirmation methods can be added before determining the target physical destination port matched by the target optical transmission link in step S1, as follows:

[0070] The first type

[0071] S10. Receive alarm information used to characterize the interruption of the target optical fiber core, the interruption of the target optical transmission section, and / or the interruption of the target optical monitoring channel.

[0072] Specifically, it can receive alarm information provided by the alarm and fault management module and the fault event monitoring module;

[0073] It can analyze whether each alarm message indicates the existence of an optical fiber core interruption event, an optical transmission segment interruption event, and / or an optical monitoring channel interruption event.

[0074] Specifically, an optical fiber core interruption event refers to the simultaneous occurrence of an optical transmission segment interruption event and an optical monitoring channel interruption event in the same segment.

[0075] The second type

[0076] S10. Receive a cutover work order that characterizes the cutting of the target optical fiber core, target optical transmission segment, target transmission topology link and / or target optical monitoring channel.

[0077] Specifically, it can receive cutover work orders provided by the cutover process monitoring and management module;

[0078] It can analyze whether each cutover work order represents a physical link cutover plan for the target optical transmission link or a transmission network element entity cutover plan in the target optical transmission link.

[0079] Among them, the transmission network element entity can be an entity such as a transmission network element device, a board, or a port object.

[0080] A port object can be a physical interface used for receiving and transmitting optical and electrical signals.

[0081] As can be seen from the above technical solution, compared with the previous embodiment, this embodiment adds a new optional method for confirming the target optical transmission link interruption event. Through this method, the target optical transmission link interruption event can be pre-determined using the aforementioned alarm information and cutover work order. The diversified confirmation methods enable this application to adapt to more complex and varied practical application scenarios, improving the flexibility and practicality of alarm compression.

[0082] In some embodiments of this application, the process of step S2, obtaining an information storage table for recording physical transmission link information, logical bearer link information, and intra-site transmission link information in the optical transmission network, is described in detail below:

[0090] The second information field can be derived from the EMS-side device configuration and updated and synchronized in real time using the EMS-side device configuration.

[0091] S21. Obtain a storage table for recording the first identification information and first configuration parameters of different optical multiplexing sections (OMS), the second identification information and second configuration parameters of different optical channels (OCH), and the third identification information and logical bearer link of different protection groups; wherein, the target configuration parameters include, but are not limited to: source and destination network element ports; the target configuration parameters are the first configuration parameters and the second configuration parameters.

[0092] Specifically, each first identification information may include the ID and name of the corresponding OMS.

[0093] Each first configuration parameter may include the direction of the corresponding OMS, the OTS segment bearer sequence, the EMS network management system and source and destination network element ports, the source station and the destination station, and whether to configure OMSP protection or OLP protection, etc.

[0094] The direction can be divided into one-way or two-way.

[0095] The OTS segment carrying sequence may include identification information for one or more OTS segments.

[0098] The OMS bearer sequence may include one or more OMS identification information segments.

[0099] Each third identification information may include the ID and name of the corresponding protection group.

[0100] The protection type can be OLP, OMSP, or OCHP.

[0101] Relevant information can be obtained from the EMS network management system corresponding to different technical systems.

[0102] S22. Obtain the station transmission link storage table used to record the topology connection relationship between boards within the network element and the cross-connection relationship between ports within the board.

[0103] Specifically, the in-station transmission link storage table can be used to describe the transmission path of signal flow within the communication station.

[0104] The on-site transmission link storage table can be built based on transmission equipment configuration, single-board fiber connection relationship, or design drawings.

[0105] S23. Integrate the physical transmission link storage table, the logical bearer link storage table, and the intra-station transmission link storage table to generate the information storage table.

[0106] Specifically, the information in the physical transmission link storage table, logical bearer link storage table, and intra-site transmission link storage table can be cleaned and integrated to generate an information storage table.

[0107] As can be seen from the above technical solution, this embodiment provides an optional method for obtaining an information storage table that records physical transmission link information, logical bearer link information, and intra-site transmission link information in an optical transmission network. This method allows for the detailed and accurate acquisition of various key information within the optical transmission network, providing a solid data foundation for subsequent alarm compression operations.

[0108] In some embodiments of this application, the process of obtaining the site transmission link storage table for recording the topological connection relationship between network elements and the cross-connection relationship between ports within the network element is described in detail. The steps are as follows:

[0109] S220. Determine all network element internal boards and all internal ports of each network element internal board within each communication station.

[0110] Specifically, all communication stations included in the optical transmission network can be identified;

[0111] The second information field can be used to determine all network element boards within each communication station and all board ports within each network element board.

[0112] S221. Determine the topological connection relationship between different network element boards and the port connection relationship within the same communication station.

[0113] Specifically, the topological connection relationship between boards within different network elements and the connection relationship of ports within the same communication station can be determined through equipment configuration, board fiber connection relationship or design drawings.

[0114] S223. Based on the topological connection relationship between different network element boards in different communication stations and the connection relationship of the board ports, construct a station transmission link storage table.

[0115] Specifically, an intra-station transmission link storage table can be constructed based on the relationships between various communication stations in the optical transmission network, combined with the topological connection relationships between boards of different network elements within different communication stations and the port connection relationships within the boards.

[0116] As can be seen from the above technical solution, this embodiment provides an optional method for obtaining an intra-site transmission link storage table that records the topological connection relationships between boards within a network element and the cross-connection relationships between ports within a board. Through this method, the intra-site transmission link storage table can characterize the signal flow within the station, providing crucial data support for alarm compression, enabling more accurate location of affected target transmission topology segments and adjacent ports, thereby achieving efficient alarm merging and compression.

[0117] As can be seen from the above technical solution, this embodiment provides an optional method for determining all target transmission topology segments that are mapped to the target physical port based on the mapping relationship between different transmission physical ports and different transmission topology segments in the information storage table. Through this method, all target transmission topology segments affected by the interruption of the target optical transmission link can be quickly and accurately located, improving the efficiency and accuracy of the operation, ensuring that the alarm compression process can proceed smoothly and efficiently, and thus improving the response of the entire optical transmission network fault handling.

[0118] In some embodiments of this application, step S4, which involves determining all adjacent ports affected by the interruption of the target optical transmission link by taking each target transmission topology segment as the transmission starting point and combining the logical bearer link information in the information storage table with the intra-site transmission link information, is described in detail below:

[0119] S40. The physical ports corresponding to each target transmission topology segment are designated as adjacent ports.

[0120] Specifically, the source and destination ends of each target transmission topology segment can be determined based on the information storage table. Each source and destination end is then cleaned to obtain multiple adjacent ports.

[0121] S41. Based on the information storage table, detect whether each target transmission topology segment corresponds to a subsequent transmission topology segment and / or a bearer transmission topology segment; if so, determine multiple adjacent ports based on the subsequent transmission topology segment and the bearer transmission topology segment of each target transmission topology segment.

[0122] Specifically, based on the information storage table, it can be determined whether each target transmission topology segment belonging to the OTS corresponds to a subsequent topology segment and / or a bearer transmission topology segment;

[0123] If so, the subsequent transmission topology segments and / or the source and destination ends of the carrying transmission topology segments of each target transmission topology segment are cleaned to obtain multiple adjacent ports.

[0124] If not, no action is required.

[0125] As can be seen from the above technical solution, this embodiment provides an optional method to determine all adjacent ports affected by the interruption of the target optical transmission link by sequentially taking each target transmission topology segment as the transmission starting point and combining the logical bearer link information in the information storage table with the intra-site transmission link information. Through this method, the accuracy and completeness of adjacent ports are greatly improved by a progressive and comprehensive investigation.

[0126] In some embodiments of this application, the process of detecting whether each target transmission topology segment corresponds to a subsequent transmission topology segment and a carrying transmission topology segment based on the information storage table in step S41 is described in detail, and the steps are as follows:

[0127] S410. For each target transmission topology segment, find all target OMS paths and all target OCH paths carried in the target transmission topology segment as the carrying transmission topology segment of the target transmission topology segment; determine whether the target transmission topology segment belongs to an intermediate relay segment in the corresponding target OMS path. If so, take all OTS channels in the corresponding target OMS path that are subsequent to the target transmission topology segment as each subsequent transmission topology segment.

[0128] Specifically, since OSC does not carry service signals, for each target transmission topology segment, if the target topology type of the target transmission topology segment is OTS, then according to the bearer sequence of each OTS segment and the direction of OMS in the information lookup table, all OMS carried in the target transmission topology segment can be determined as each target OMS path; according to the bearer sequence of each OMS in the information lookup table, all OCH carried in each target OMS path can be determined as each target OCH path; each target OCH path can be used as a bearer transmission topology segment indirectly carried in the corresponding target transmission topology segment, and each target OMS path can be used as a bearer transmission topology segment directly carried in the corresponding target transmission topology segment.

[0129] It can be determined whether each target transmission topology segment belongs to an intermediate relay segment. If so, the subsequent OTS channels of the target transmission topology segment in the OTS segment bearer sequence corresponding to each target transmission topology segment of the target topology type OTS can be used as each subsequent transmission topology segment. The same segment transmission links of each target transmission topology segment of the target topology type OSC can be found as its corresponding subsequent transmission topology segments.

[0130] As can be seen from the above technical solution, this embodiment provides a method for detecting whether each target transmission topology segment corresponds to a subsequent transmission topology segment and an optional carrier transmission topology segment based on the information storage table. Through this method, deterministic derivation based on physical connections and configuration relationships is possible, without fuzzy associations, ensuring the accuracy of the results. Impact surface analysis is completed in milliseconds, far faster than manual investigation and traditional association algorithms.

[0131] In some embodiments of this application, the process of determining multiple adjacent ports in step S41 based on the subsequent transmission topology segments and the bearer transmission topology segments of each target transmission topology segment is described in detail, and the steps are as follows:

[0132] S410. For each bearer transmission topology segment, determine the communication station matched by the bearer transmission topology segment; take the signal port of the bearer transmission topology segment in the communication station as the in-station transmission starting point, and determine the corresponding in-station transmission endpoint matched within the communication station based on the topology connection relationship between boards within the network element and the cross-connection relationship between ports within the board.

[0133] Specifically, for each bearer transmission topology segment, the source station and destination station of the bearer transmission topology segment can be determined. The signal port of the bearer transmission topology segment in the source station is taken as the intra-station transmission start point. Based on the inter-board topology connection relationship and the cross-connection relationship between intra-board ports within the network element, the corresponding intra-station transmission endpoint is determined. Similarly, the signal port of the target OMS path in the destination station can be taken as the intra-station transmission start point. Based on the inter-board topology connection relationship and the cross-connection relationship between intra-board ports within the network element, the corresponding intra-station transmission endpoint is determined.

[0134] For the target OMS path, each intra-station transmission endpoint can be a line port in another direction connected to the corresponding target OMS path via an optical cross-connection, or it can be a port corresponding to multiple client-side ports after demultiplexing.

[0135] For the target OCH path, the transmission endpoint within each station can be the line port in another direction connected to the corresponding target OCH path via an optical cross-connection.

[0136] S411. All ports in the protection group corresponding to each target OMS path and each target OCH path, the source and destination ends of each subsequent transmission topology segment, and the intra-station transmission start point and intra-station transmission end point of each target OMS path are taken as multiple adjacent ports.

[0137] Specifically, by combining the first configuration parameters and the second configuration parameters, all ports in the protection groups corresponding to each target OMS path and each target OCH path can be determined, and all ports in the protection groups corresponding to each target OMS path and each target OCH path, the source and destination ends of each target OCH path, and the intra-station transmission start point and intra-station transmission end point of each bearer transmission topology segment can be used as multiple adjacent ports.

[0138] As can be seen from the above technical solution, this embodiment provides an optional method for determining multiple adjacent ports based on subsequent transmission topology segments and bearer transmission topology segments for each target transmission topology segment. Through this method, the adjacent port lookup process covers the physical layer, multiplexer layer, and optical channel layer, penetrating to the intra-site signal flow, ensuring no port is missed. Each derivation step has clear data association basis, which can be fully trusted and quickly understood by operation and maintenance personnel, improving the interpretability of this application's process.
